Patent GB-441544-A (GB)
Title: Improvements in the saponification of organic esters of cellulose
IPC: D06M11/38
Filed: 1934-06-16
Abstract: Cellulose acetates and other organic esters of cellulose, in particular, filaments, threads, films, &c. made of such esters, are saponified either by treatment with a solution containing ammonia and a mineral saponifying agent, or by carrying out the first part of the saponification with ammonia and then immediately completing the saponification by a mineral saponifying agent.  By these methods a relatively deep-seated saponification may be effected at a rapid rate, and the products may posses a high tenacity and good extensibility.  The concentration of the ammonia should be high, say, of 30--45 per cent, and the saponification may be carried out under pressure as described in Specification 435,806, so permitting high concentrations of ammonia to be employed.  Relatively small amounts of mineral saponifying agent suffice.  In the two stage process it is an advantage to reduce the acidyl groups in the first stage to 1\ba1/2\be to 1 per C6H10O5 unit.  The saponifying agents are preferably employed in aqueous solution although alcoholic or aqueous-alcoholic media may be used.  In examples, cellulose acetate yarn is treated with 30--40 per cent aqueous ammonia containing 2--4 per cent caustic soda at 80--120 DEG  C. under 5--10 atmospheres pressure; or alternatively it is treated under the same conditions with 30--40 per cent aqueous ammonia and then with 1--3 per cent aqueous caustic soda at 90--100 DEG  C.  Specifications 207,562 and 323,790, [both in Class 2 (ii)], and 340,324, 340,325, 340,326, 340,436, 340,437, 343,062, 370,430, 371,461, 378,858 389,823, 438,584, 438,585, 438,586, and 438,587 also are referred to.
